0027386: BRepOffsetAPI_MakePipeShell does not provide history of generations
The method BRepOffsetAPI_MakePipeShell::Generated now returns generated shapes for sub-edges and sub-vertices of sections. The method BRepFill_PipeShell::BuildHistory is redesigned: now it builds generated shapes for sub-edges and sub-vertices of sections. New Draw command "gensweep" is added to sweep commands for testing of history building.
